Try with this :

ruletype my_alert {
type alert
output log_unified2 : filename snort_unified.log, limit 128
output alert_syslog : LOG_AUTH LOG_ALERT
}

my_alert tcp $EXTERNAL_NET any -> $HTTP_SERVERS $HTTP_PORTS (msg:"ET WEB_SPECIFIC_APPS User Agent (SQLi Injection / Scanning)"; flow:established,to_server; content:"User-Agent|3a 20|testitest"; http_header; fast_pattern; reference:url,en.wikipedia.org/wiki/SQL_injection<http://en.wikipedia.org/wiki/SQL_injection>; classtype:web-application-attack; sid:2023351; rev:1; metadata:attack_target SQL_Server, created_at 2016_10_19, deployment Datacenter, performance_impact Low, signature_severity Major, updated_at 2020_07_31;)

Hello,


You forbid to log to a program with underscore then the program who is use as a log :

For example with syslog :

log_syslog

Finally if unified and syslog are use as a logger your rule is typed like these :

output unified2: filename snort_unified.log, limit 128

ruletype my_alert {
type alert
output unified2 log_unified2 : filename snort_unified.log, limit 128
output alert_syslog log_syslog : log_auth log_alert
}

my_alert tcp $EXTERNAL_NET any -> $HTTP_SERVERS $HTTP_PORTS (msg:"ET WEB_SPECIFIC_APPS User Agent (SQLi Injection / Scanning)"; flow:established,to_server; content:"User-Agent|3a 20|testitest"; http_header; fast_pattern; reference:url,en.wikipedia.org/wiki/SQL_injection<http://en.wikipedia.org/wiki/SQL_injection>; classtype:web-application-attack; sid:2023351; rev:1; metadata:attack_target SQL_Server, created_at 2016_10_19, deployment Datacenter, performance_impact Low, signature_severity Major, updated_at 2020_07_31;)

I hope success your problem,
